Functions

func CopyFields 

func CopyFields(dst, src interface{}) (err error)

CopyFields copies matching struct/array/slice fields that implement the Value interface from src to dst. Matching is done by comparing the MetaData.Selector() of the fields. Copying is done by calling SetString() of dst with the result from String() of src. This way even not exactly matching models can be copied by converting to and from strings if this is possible without errors.

func CopyFieldsIfNotEmpty 

func CopyFieldsIfNotEmpty(dst, src interface{}) (err error)

CopyFieldsIfNotEmpty copies matching struct/array/slice fields that implement the Value interface from src to dst, if IsEmpty() of src returns false. Matching is done by comparing the MetaData.Selector() of the fields. Copying is done by calling SetString() of dst with the result from String() of src. This way even not exactly matching models can be copied by converting to and from strings if this is possible without errors.

type Iterator 

type Iterator interface {
	// Next tries to unmarshalles the next iteration's data into resultRef
	// and returns a bool indicating if it was successful.
	// After Next() has returned false, check the result of Err().
	Next(resultRef interface{}) bool

	// Err returns the error of the last iteration.
	// Err returns nil if the last iteration was successful,
	// or there was no last iteration.
	Err() error
}

Iteration stops with Next() == nil, check Err() afterwards.

Be careful when using the address of a local variable for resultRef in a loop that creates a closure function that will be called later for rendering. Go does not make copies of variables that are bound to closure, but references them. If a closure is called outside of the loop, it will always reference the same variable with the value from the last Next() call in it.

func (*MetaData) Attrib 

func (self *MetaData) Attrib(tagKey, name string) (value string, ok bool)

The meaning of attributes is interpreted by the package that reads them. Attributes are defined in a struct tag named "gostart", "model" or "view" and written as name=value. Multiple attributes are separated by '|'. Example: 

type Struct {
	X int `model:"min=0|max=10"`
	S []int `model:"maxlen=3|min=0|max=10"
	hidden int
	Ignore int `gostart:"-"`
